Summary by Directory Macro Finance - **Index Futures**: Influenced by international trade issues, Fed policy expectations, and domestic market conditions, A - share new account openings increased in July, and the market may fluctuate slightly during the mid - report disclosure period in late August. Index futures are expected to fluctuate [6]. - **Treasury Bonds**: After the announcement of the resumption of VAT on bond interest income, the short - term impact on the bond market is limited.

Cotton Textile Industry Chain - **Cotton and Cotton Yarn**: The global cotton supply and demand are increasing, and the Xinjiang output is expected to be good. The downstream consumption is weak, and the price is expected to fluctuate and adjust [36]. - **Apples**: The spot market is weak, the new fruit growth is normal, and the price is expected to fluctuate weakly [36]. - **Jujubes**: In the growth period of jujube trees, the futures price is expected to fluctuate weakly in the short term, and attention should be paid to new developments in the production area [37]. Agricultural and Livestock - **Pigs**: The short - term price is supported by farmers' resistance to price cuts and secondary fattening, but the long - term supply is increasing. Different contracts have different trends, and attention can be paid to the long 05 and short 03 arbitrage [39][41]. - **Eggs**: The short - term supply is affected by high - temperature weather, and the demand is expected to increase seasonally, but the supply pressure is large. The 09 contract is recommended to go short at high prices, and the 12 and 01 contracts can be considered to go long on dips [41][43]. - **Corn**: The short - term supply - demand game is intense, and the price is expected to range between 2250 - 2350. Attention can be paid to the 9 - 1 reverse arbitrage [43][44]. - **Soybean Meal**: In the short term, the supply is abundant, and the price increase is limited. In the long term, there may be a supply gap, and it is recommended to go long on dips for some contracts [46]. - **Oils**: The short - term risk of a high - level callback is increasing, but the callback range is limited. It is recommended to take profits on existing long positions and pay attention to the soybean - palm oil 09 spread rebound strategy [47][51].
